http://www.imagehosting.com/out.php/i412805_ramp.JPG - The angle between the ramp and horizontal is 60 degrees. - The hanging mass has a mass of 1.5 kg - The mass on the ramp has a mass of 0.4857 kg - When the system is moving, it has an acceleration of 4.915 m/s^2. Determine the tension on the string when: a) The system is not moving b) The system is released and free to move a) I believe that the tension force on the rope would be 14.7 N (1.5 kg * 9.8 m/s^2), as the hanging mass is pulling the rope whereas the stationary ramp mass acts as an anchor. b) [tex]\Sigma F = ma [/tex] [tex]\Sigma F = F_(gravity) - F_(tension) [/tex] [tex] F_g - F_t = ma [/tex] [tex] 14.7 N - F_t = (1.5 kg)(4.915 m/s^2) [/tex] [tex] F_t = 7.33 N [/tex] I am not too sure about the second answer, as I'm not really certain whether the mass in the 'ma' expression should be the entire system mass, or whether I have actually done the entire thing correctly in the first place... Thanks for any help!!
